the notion of RULES in music bothers me a lot
music has no rules, dare i say it’s not a science so don’t approach it as one but even then science isn’t rule based, science is very maluable, physics has changed so much over centuries, as has music
music has different styles, purposes, genres
and all of these have conventions, intents and affects (or Der Affekt [pl. Die Affekte] {faux middle english afecte, afecten}]
there are no rules, some styles may implicate rules, or state some
but that makes u either following the rules of a style
or in other terms, being more idiomatic to a style, more conventional, following the conventions of a style
it comes up mostly in the teaching of common practice period music theory [europe 17-20th century art music / classical music {choose ur poison, i’m indifferent}]
they bring up examples of "rule-breaking", yet they show only examples of where the broken rule (parallel fifths) either don’t apply to the given affect or intention (take german 6 resolving without and intermittent 6/4 chord, not uncommon in classical era; often in chordal or homophonic textures, doesn’t sound odd ass parallel fifths are a contrapuntal aversion (dare i say an adversion [goes against core principal of <species> counterpoint—that being independent melodies]), not as important in non polyphonic contexts)
and to me this shows a lack of understanding of why we teach and create theory
or what it is on a whole, it isn’t a how to be a musical person, how to be the best musician, yet when we are working, breaking of these rules are seen as idiotic or unmusical
i am annoyed but this stems from my experience in historical performance as a classical musician (keyboard and voice primarily both 1300-1600s) and also as someone who deals a lot with ethnomusicology
